The SY55851A is a highly flexible, universal logic gate
capable of up to 3.0GHz operation. This AnyGate
differential logic device will produce all possible logic
functions of two Boolean variables. It can be configured
as any of the following gates: AND, NAND, OR, NOR,
XOR, XNOR, DELAY, NEGATION (NOT). The
SY55851A can also function as a 2-input multiplexer.

FUNCTIONAL DESCRIPTION
2.1
Establishing Static Logic Inputs
The true pin of an input pair is internally biased to
ground through a 75kresistor. The complement pin of
an input pair is internally biased to VCC/2 through an
internal voltage divider consisting of two 75k
resistors. Since some logic functions necessitate an
output to be connected to two inputs, SY55851A inputs
have no internal terminations. For typical terminations
see Section 5.0, Input Interface Applications.
VCC
Input
NC
/Input
To keep an input at static logic zero at VCC 3.0V,
leave both inputs unconnected or tie the complement
input to VCC. For VCC < 3.0V applications, connect the
complement input to VCC and leave the true input
unconnected. These are the only safe ways to cause
inputs to be at a static value. In particular, no input pin
should be directly connected to ground. All NC (No
Connect) pins should be unconnected.
